Abstract: An apparatus for connecting two generators to run in parallel including a conductive path that connects the generators to an electrical load, a switching circuit that opens/closes the conductive path, a current sensor that detects current flowing the conductive path and an electronic control unit comprising a microcomputer. The control unit functions as a generator model identifier that inputs a signal indicating a model ID from each generator and determines whether the model ID corresponds to data stored in memory, and a switching circuit operator that operates the circuit to close the conductive path to connect the generators to the electrical load when the model ID corresponds to the data, while operates it to open the conductive path when the current is not detected by the current sensor after the conductive path was closed, thereby preventing the outputs of other generators from appearing at the terminals of a disconnected plug and damage to the generators.

Abstract: An electronic control unit includes a printed wiring board (50), electronic components (51 to 53) mounted on the printed wiring board (50), and a synthetic resin coating (57) formed by injection molding to cover the printed wiring board (50) and the electronic component (51 to 53). The electronic components (51 to 53) are housed in a protective case (75) that can resist pressure and heat during the injection molding of the coating (57). Thus, in the electronic control unit, an electronic component is not damaged by formation of a coating by injection molding so that the electronic control unit can always function normally.

Abstract: A resin encapsulated electronic component unit and method includes a printed wiring board, mounted electronic components, and a resin coating layer, which covers and encapsulates the electronic components by insert molding. The resin coating layer is formed from a thermoplastic resin. The resin encapsulated electronic component unit includes accessory members, which are molded from the thermoplastic resin. The insert molding is performed by use of molds including cavities in which the board is disposed and hollow portions corresponding to the accessory members and by injecting the thermoplastic resin into the hollow portion and discharging air from the hollow portion so that the thermoplastic resin flows longitudinally of the board. The resin coating layer is disposed on both front and back surfaces of the board and the amount of thermoplastic resin is substantially symmetrically disposed on both front and back surfaces of the board.

Abstract: An operating condition of an outboard motor 1 is detected by an ECU 3, and then, is transmitted to a remote monitoring apparatus 6 using a mobile phone 5. The condition data transmission is made by only access from the outboard motor 1 side, therefore, security can be secured. When confirming a failure based on the condition data, the remote monitoring apparatus 6 decides the cause of failure by troubleshooting, and then, give information about measures to a boat 2 equipped with the outboard motor 1. Troubleshooting is carried out by acquiring a program from a server of maker, and the cause of failure is transmitted to the server so as to be stored as user information. The remote monitoring apparatus 6 orders necessary maintenance parts so as to improve quickness of maintenance.

Abstract: A system for detecting reverse rotation of a 4-cycle, internal combustion engine with three or more cylinder for an outboard motor mounted on a boat, whose output is connected to a propeller such that the boat is propelled forward or reverse. In the system, it is determined whether a counted value of crank angle signals generated once every 30 crank angles is a multiple of a predetermined number (e.g., four in six cylinders), when the cylinders are identified and it is determined that engine rotates reverse when the counted value is determined to be not the multiple and the engine is immediately stopped. With this, it becomes possible to accurately detect the reverse rotation of the engine and prevent its further reverse rotation.

Abstract: An oil pressure warning system for an outboard motor for detecting and alarming an abnormal oil pressure of an internal combustion engine, the system including a first oil pressure switch which generates an ON signal when the oil pressure is less than or equal to a first predetermined oil pressure, and a second oil pressure switch which generates an ON signal the oil pressure is less than or equal to a second predetermined oil pressure set higher than the first predetermined oil pressure. The abnormality of oil pressure is detected and alarmed based on the ON signal of the switches. The first and second predetermined oil pressures are determined based on an oil pressure characteristic of a (possible) maximum oil temperature (under which the engine has been warmed up) set relative to the engine speed, thereby ensuring to detect and alarm the abnormality of oil pressure under any engine speed and any oil temperature.

Abstract: An idling speed control system for an outboard motor mounted on a boat and equipped with an internal combustion engine, whose output is connected to a propeller through a clutch, having secondary air supplier that supplies secondary air. In the system, the engine start-state as to whether the engine has been started is determined and the clutch position is detected and based thereon, the desired idling speed and the desired secondary air supply amount is determined through learning control. With this, the system can therefore accurately determine the desired idling speed and the desired secondary air supply amount and achieve steady idling speed even if load changes owing to a change in clutch position or propeller replacement.
